AI总结：
本文针对在线社交网络中野生动物制品促销行为的检测与识别问题，构建了可扩展数据集并利用多模态机器学习框架自动识别可疑销售帖子和账户，深入分析系统化销售行为，为打击非法野生动物交易提供支持。
摘要：
野生动物贩运（WLT）已成为一个全球性问题，贩运者将其活动从线下扩展到在线平台，利用电子商务网站和社交网络来促进其非法交易。本文致力于解决在线社交网络中检测和识别野生动物制品促销行为的挑战，这是打击这些破坏环境活动的关键环节。为了应对这些破坏环境的非法活动，本研究聚焦于在线社交网络中的野生动物制品促销行为。具体而言：1）采用基于网络的方法收集了一个与野生动物制品交易相关的可扩展数据集。该数据集通过人在回路的机器学习过程进行标注，区分包含野生动物制品销售帖子的正类样本，以及被误分类为潜在WLT帖子但随后由人类标注员纠正的困难负样本（代表正常帖子）。2）我们在所提出的数据集上对机器学习结果进行了基准测试，并构建了一个实用框架，该框架充分利用在线社交网络的多模态特性，自动识别可疑的野生动物销售帖子和账户。3）本研究深入分析了交易帖子，揭示了当前普遍存在的系统化和有组织的销售行为。我们提供了对这些行为本质的详细见解，为理解和打击非法野生动物制品交易贡献了宝贵信息。
英文摘要：
Wildlife trafficking (WLT) has emerged as a global issue, with traffickers expanding their operations from offline to online platforms, utilizing e-commerce websites and social networks to enhance their illicit trade. This paper addresses the challenge of detecting and recognizing wildlife product sales promotion behaviors in online social networks, a crucial aspect in combating these environmentally harmful activities. To counter these environmentally damaging illegal operations, in this research, we focus on wildlife product sales promotion behaviors in online social networks. Specifically, 1) A scalable dataset related to wildlife product trading is collected using a network-based approach. This dataset is labeled through a human-in-the-loop machine learning process, distinguishing positive class samples containing wildlife product selling posts and hard-negatives representing normal posts misclassified as potential WLT posts, subsequently corrected by human annotators. 2) We benchmark the machine learning results on the proposed dataset and build a practical framework that automatically identifies suspicious wildlife selling posts and accounts, sufficiently leveraging the multi-modal nature of online social networks. 3) This research delves into an in-depth analysis of trading posts, shedding light on the systematic and organized selling behaviors prevalent in the current landscape. We provide detailed insights into the nature of these behaviors, contributing valuable information for understanding and countering illegal wildlife product trading.
